This IC must be a timer which is found in a flowmeter. Can anyone help me identify it.
Things written on it are 397C1 3310D 1611CM

3\$\begingroup\$ Why do you think "it must be a timer"? It's much more likely to be an MCU. \$\endgroup\$– TransistorJan 20, 2018 at 7:00

\$\begingroup\$ Those 'JTAG pins' are badly soldered (at least that's what I presume them to be) \$\endgroup\$– Voltage Spike ♦Jan 20, 2018 at 7:25

1\$\begingroup\$ @laptop2d Could those be press-fit connectors? I've never seen them personally, so just a wild guess ;) \$\endgroup\$– AdrianoKFJan 20, 2018 at 9:41

It's a nordic semiconductor bluetooth chip. I don't know exactly which one, but if you want you can look through all their datasheets to find the product markings, and one of them will match up. There's also a chip antenna at the top of the picture.

\$\begingroup\$ Is it really a chip antenna? Looks to me like one of these 32-ish kHz crystal packages. Its placement also doesn't scream antenna to me. \$\endgroup\$ Mar 28, 2018 at 7:40
